CYNTEC CO., LTD. 乾坤科技股份有限公司乾坤科技股份有限公司乾坤科技股份有限公司乾坤科技股份有限公司 Sep., 2017 DOCUMENT : SDET32251B-000 REVISION : A5 PAGE : 2 OF 3 /square6 Specifications Part Number Inductance ( µ H ) @ (0A) Rdc ( m Ω ) Heat Rating Current DC Amps. Idc ( A ) Saturation Current DC Amps. Isat ( A ) Typical Maximum Typical Maximum Typical Maximum *： If you require another part number please contact with us. ** ： Inductance Tolerance ± 20% Note 1. ： All test data is referenced to 25 ℃ ambient. Note 2. ： Test Condition:1MHz, 1.0Vrms Note 3. ： Idc : DC current (A) that will cause an approximate △T of 40 ℃ Note 4. ： Isat : DC current (A) that will cause L0 to drop approximately 30% Note 5. ： Operating Temperature Range -55 ℃ to + 125 ℃ Note 6. ： The part temperature (ambient + temp rise) should n ot exceed 125 ℃ under the worst case operating conditions. Circuit design, component placement, PC B trace size and thickness, airflow and other cooli ng provision all affect the part temperature. Part temperature should be verified in the end application. Note 7. ： The rated current as listed is either the saturatio n current or the heating current depending on which value is lower.
